Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas cooker, and more particularly to a gas cooker capable of selectively performing an oven function and a grill function by using one burner.

[0002]

2. Description of the Related Art There are various types of cookers that use gas, such as a natural convection oven range, a grill range, and a combined-use oven range. The oven range is a burner at the bottom of the cooking chamber. Is provided to perform the oven function, and the grill range is provided with a burner at the top of the cooking chamber to perform the grill function.

A cooking device provided with one burner is designed to perform a single function as its cooking method, namely, only an oven function in a microwave oven and a grill function in a grill oven. There is an inconvenience that a separate cooking utensil must be provided to perform the oven and grill functions.

Further, recently, a cooker provided with two burners and having both an oven function and a grill function has become widespread. That is, in such an oven and grill cooker, a burner for the grill and a burner for the oven are separately provided at the upper and lower portions of the cooking chamber, and a dish pan is installed between the burner for the grill and the burner for the oven. However, a heat reflection plate that reflects the combustion heat of the burner downward toward the food is provided above the grill burner. Further, between the burner for the oven and the cooking saucer, there is provided a heat radiating plate that functions as a screen so that the combustion heat from the oven burner is not directly applied to the cooking food, that is, is indirectly transmitted. . Depending on the type of cooking, the burner for the grill or the burner for the oven is selectively used to selectively perform the grill function or the oven function, respectively.

A typical example of such a cooking device is Shokai Sho6.
No. 1-1002. In this conventional cooker, burners are installed on the ceiling and bottom of the cooking chamber, respectively, and a heat diffusion plate is provided in the center of the ceiling so as to cover the ceiling burner and maintain a constant distance from the ceiling. ing. The heat diffusion plate has a cup-shaped cross section in which the central portion is concave, and a large number of holes are formed at regular intervals in the vertical and horizontal directions. The heat diffusion plate extends from the front surface to the rear surface of the cooking chamber, and its width is formed to be shorter than the width between the side walls of the cooking chamber. Further, the heat diffusion plate is adapted to be inserted into the heat adjustment plate, and this heat adjustment plate has a hollow portion and forms an internal space into which the heat diffusion plate can be tightly inserted. . Further, a large number of holes are formed in the heat preparation plate in the same pattern as the holes formed in the heat diffusion plate. Then, when the heat diffusing plate is inserted into the hollow part of the heat adjusting plate and slid, the holes of the heat diffusing plate and the holes of the heat adjusting plate are opened to coincide with each other, or the positions of these holes are shifted and the holes are moved. Are to be closed. In this way, the heat amount applied to the cooked product is adjusted by the heat diffusion plate and the heat adjusting plate located between the ceiling burner and the cooked product, and the heat amount suitable for the cooking state is added to the cooked product.

However, in such a conventional cooker, two burners are provided on the upper and lower sides of the cooking chamber, and the reflector and the heat radiating plate are installed on the upper side of the cooking chamber. There is a problem that the internal structure becomes complicated, the space volume that can be utilized in the cooking chamber is reduced, and since two burners are used, the material cost becomes high.

Further, in Japanese Unexamined Patent Publication No. 52-108269, an upper burner is arranged in the upper part of the cooking chamber, lower burners are arranged on both sides of the lower part of the cooking chamber, and soaking is performed above each lower burner. Disclosed is a gas cooker in which a plate is slidably arranged, and when this heat equalizing plate is slid toward the center of a cooking chamber, a hot air flow passage for an oven is provided on the cooking chamber wall side of the heat equalizing plate. Has been done.

However, even in this conventional cooker, since three burners are installed at the upper and lower parts,
There is a problem that the manufacturing cost becomes high. Furthermore, since two heat equalizing plates corresponding to the two lower burners installed on both sides of the cooking chamber are separately installed on the left and right sides of the cooking chamber, the means for sliding the respective heat equalizing plates are cooked. Since it has to be separately provided on both the left and right sides of the chamber, and further a synchronizing means must be installed in order to synchronously slide the two heat equalizing plates, the structure becomes extremely complicated and However, there is a problem that the available space volume in the cooking chamber is significantly reduced because the installation space is required.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the conventional cooking device as described above, and an object of the present invention is to have an oven function and a grill with a single burner. (EN) It is possible to provide a gas cooker which can selectively perform a function, has a simple structure, and can sufficiently secure a space volume in a cooking chamber.

[0010]

In order to achieve the above object, an oven and grill gas cooker according to the present invention has an inner cooking chamber and side walls spaced apart in the width direction of the cooking chamber. , The side wall has a supporting means for supporting a dish to be cooked, and a case in which a cavity is formed in one of the side walls, a gas burner arranged in the lower part of the cooking chamber, and a side wall of the case facing each other Groove means formed on the surface to be, and heating control means which is located between the burner and the support means and which opens and closes the passage of the flame from the burner to the cooking pan, the heating control means, A plurality of heating control members that are inserted into the groove means and that have an opening portion that forms the flame passage, the heating control member being relatively slidable so that the flame passage can be selectively closed; , The cavity An operating rod that is rotatably installed in the pin and is pin-and-slot connected to one of the heating control members, wherein the heating control member is relatively slid by rotating the operating rod. An actuating rod and a relative sliding movement of the heating control member to selectively open the flame passage to perform a grill function and close the flame passage to perform an oven function. And operating means for rotating the operating rod.

That is, in the gas cooker of the present invention, a cooking chamber is formed in a substantially rectangular parallelepiped case, and a saucer on which food is placed is detachably supported at an intermediate portion of the cooking chamber. At least two heating control members are provided between them. The heating control member is composed of a pair of frames and a plurality of panels, and the panels are fixed to the frame with the same spacing as the width of the panels. A pin-shaped projecting member provided on one of the heating control members is inserted into the slot of the operating rod and is slot-and-pin connected. The operating rod is connected to the operating knob via a rotary shaft. Therefore, when the operation knob is rotated, the operating rod is also rotated and one heating control member is shifted with respect to the other heating control member. Then, the panels of the upper and lower heating control members are placed in a positional relationship where they are displaced from each other or in a positional relationship where they overlap each other. If the upper and lower panels are placed in a positional relationship that is offset from each other, the heat from the burner is blocked from being directly applied to the pan according to the degree of the offset, and cooking is performed by radiation and convection through the heating control member. Since the heat is transferred to the food, the food is evenly heated to perform the oven function. On the other hand, when the upper and lower panels are placed in a positional relationship in which they overlap each other, the flame of the burner is directly added to the dish pan through the gap between the panels,
The grill function is executed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an embodiment of a gas cooker according to the present invention. This gas cooker has a cooking chamber 1
And a gas stove 2 installed above the cooking chamber and a tableware dryer 3 installed below the cooking chamber.

In the lower part of the cooking chamber 1, one burner 4 is installed as in the conventional oven cooker. A supporting member 10 is formed on both side walls 12 and 14 of the cooking chamber 1 so as to project from the bottom surface of the cooking chamber at a constant height, and a tray 5 on which a food item is placed is supported by the supporting member 10 so as to be drawn out. . The support member 10 is arranged at a predetermined height position above the burner 4 with a gap. Further, the tray 5 may have a mesh shape.

Heating control means 6 is installed between the pan 5 and the burner 4. The heating control means 6 includes an upper heating control member 6a and a lower heating control member 6b, and the upper heating control member 6a is supported by grooves 90, 90 'formed in both side walls 12, 14 of the cooking chamber 1, and The lower heating control member 6b is a groove 9 formed in both side walls 12 and 14 of the cooking chamber 1.
It is supported by 1, 91 '. In this example,
Although two heating control members are illustrated, the present invention is not limited to this, and three or more heating control members can be installed.

The heating control means 6 is shown in detail in FIGS. The upper heating control member 6a includes a pair of parallel frames 61a, 61a, and the space S between the frames is the depth of the cooking chamber (depth from the front surface to the rear wall).
The length Z of the frame is shorter than the left and right side walls 1 of the cooking chamber 1.
It is longer than the width W between 2 and 14. Further, the upper heating control member 6a includes a plurality of panels 62a.
2a are arranged and attached on the frame 61a at the same intervals so as to be orthogonal to the frame 61a. Each panel 62a is
It is a rectangular plate that is longer than the space S between the frames and shorter than the depth of the cooking chamber. Further, a pin-shaped projecting member 63 projects at a right angle from the vicinity of one end of one frame 61a. The protruding member 63 has a diameter smaller than the diameter of the frame 61a and a predetermined length.

The lower heating control member 6b has substantially the same structure as the upper heating control member 6a, but a frame 61b is used.
Is shorter than the frame 61a of the upper heating control member, the panel 62b attached to the frame 61b
And the frame 61b is not provided with a protruding member, which is different from the upper heating control member 6a.

The interval Y between the upper heating control member panel 62a and the panel 62a and the lower heating control member panel 62b.
The distance between the panel and the panel 62b is the same as the width X of the panel. Therefore, as will be described later, by shifting the upper heating control member 6a with respect to the lower heating control member 6b, the heating control means 6 selectively forms a flame passage for directly applying the flame of the burner 4 to the saucer. Or this flame passage is cut off.

On both side walls 12 and 14 of the cooking chamber 1, horizontal grooves 90, 90 ', 91 and 91' which are longer than the space S (FIG. 2) between the frames of the heating control member are formed.
The frame 61a of the upper heating control member 6a and the frame 61b of the lower heating control member 6b have grooves 90 and 90 ', respectively.
And 91, 91 'are inserted and supported. In this way, the upper and lower heating control members 6a and 6b are vertically adjacent to each other while being supported by the grooves 90, 90 'and 91, 91' of the side walls 12 and 14, respectively.

The upper grooves 90 and 90 'are deeper than the lower grooves 91 and 91' so that the upper heating control member 6a can be horizontally shifted to the left and right with respect to the lower heating control member 6b. Specifically, it is formed deeper than the shift distance of the upper heating control member 6a.

3 and 4, the operating rod 72 and the operating knob 7 are shown.
In the drawings, the pin-shaped projecting member 63 of the upper heating control member 6a is inserted into the slot of the operating rod 72 for slot-and-pin connection. When the operating knob 7 is rotated, the operating rod 72 is also rotated, and the operating rod 72 causes the upper heating control member 6a to reciprocate horizontally in the left and right directions. The operation knob 7 is provided on the right side of the front surface of the case near where the upper heating control member 6a is fitted.

Except for the front door, the wall of the case has a considerable thickness for the inner wall and the outer wall for heat insulation, and a heat insulating material (for example, glass fiber) is sandwiched between them to be insulated. . A cavity 18 having a predetermined size is formed in the lower portion of the right side wall. The hollow portion 18 communicates with the right upper groove 90 ′, and the right end portion of the frame 61a of the upper heating control member 6a projects into the hollow portion 18 through the upper groove 90 ′. The projecting member 63 projects forward from the right end of the frame 61a and extends at right angles to the frame 61a in the same plane as it.

In the hollow portion 18, the shaft support member 8 is fixed to the right side wall 14 with screws or the like. The rotating shaft 71 is rotatably supported by the shaft support member 8. The operating rod 72 is connected to the rotary shaft 71, and the operation knob 7 is connected to one end of the rotary shaft 71. The pin-shaped projecting member 63 of the upper heating control member 6a is slot-and-pin connected to the slot of the operating rod 72. When the operating rod 72 rotates, the projecting member 63 is displaced left and right within the slot of the operating rod 72. Further, since the operating knob 7 is connected to the operating rod 72 via the rotating shaft 71, when the operating knob 7 is rotated, the operating rod 72 also rotates by a predetermined angle. Therefore, the upper heating control member 6a slides with the rotation of the operation knob 7 while being supported by the grooves 90, 90 ', while the lower heating control member 6b is fixed in the grooves 91, 91'. .

In order to make the horizontal shift distance of the upper heating control member 6a equal to the width X of the panel 62a, it is necessary to determine the rotation angle of the operating rod 72. Therefore, the operating rod 7
With respect to a vertical line passing through the center of 2, when the left rotation angle of the operating rod 72 is θ, the panel width is X, and the length from the rotation center to the slot end of the operating rod is L, Lsin θ =
By setting X to be X, when the operation knob 7 is rotated to the left to the maximum (that is, when it is rotated to the left by the angle θ), the panel 62a of the upper heating control member 6a, ... The panels 62b, ... Are vertically overlapped with each other to form a passage (see FIG. 4). On the other hand, if the operation knob 7 is rotated to the right to match the vertical line,
The panels 62a, ... Of the upper heating control member 6a and the panels 62b, ... of the lower heating control member 6b are completely displaced from each other and the passage is closed (see FIG. 3).
The degree of displacement between the upper and lower panels can be changed according to the rotation angle of the operation knob 7.

Next, the operation based on this embodiment will be described. The saucer 5 on which the food is placed is placed on the support members 10 formed on both side walls 12 and 14 of the cooking chamber 1, and the burner 4 is ignited. At this time, the user rotates the operation knob 7 to select the grill function or the oven function.
Since the operating knob 7 is connected to the operating rod 72, the operating rod 72 also rotates as the operating knob 7 rotates. Since the protruding member 63 of the upper heating control member 6a is inserted into the slot of the operating rod 72, the protruding member 63 is pushed or pulled according to the rotation of the operating rod 72 to shift in the horizontal direction.

As shown in FIG. 3, when the operation knob 7 is rotated to the maximum clockwise, the panel 6 of the upper heating control member 6a is rotated.
2a and the panel 62b of the lower heating control member 6b are displaced from each other, and the panel 62b of the lower heating control member 6b is located at the opening (panel 6) of the upper heating control member 6a.
2a closes the space Y portion where the lower heating control member 6b is not installed, and closes the opening portion (space Y portion where the panel 62b is not installed) of the lower heating control member 6b. Therefore, the flame passage of the burner 4 installed at the bottom of the cooking chamber 1 is closed by the heating control members 6a and 6b, so that the flame of the burner 4 does not directly hit the saucer 5.

That is, the flame of the burner 4 heats the heating control members 6a and 6b, and the heated heating control members 6a and 6b are heated.
6b radiates the accumulated heat by radiation and convection. The released heat uniformly and uniformly applies heat to the entire cooking product, so that the cooker performs its function as an oven. Here, since the panels 62a and 62b are directly subjected to the flame of the gas burner 4, thermal deformation does not occur, and an iron plate plated with aluminum having good thermal conductivity is used, and the thickness thereof is set to about 0.8 mm. .

FIG. 4 shows the positional relationship of the panels when the grill function is executed in the cooker of the present invention. In this case, the panel 62a of the upper heating control member 6a and the lower heating control member 6b are shown. The panel 62b is placed in an overlapping state, the opening portions of the heating control members 6a and 6b are aligned, and the flame passage is opened. Therefore, burner 4
The flame from is directly added to the saucer through the flame passages of the heating control members 6a and 6b, and cooking by direct heat is performed.

In the above-mentioned embodiment, the upper heating control member is described as being shifted with respect to the lower heating control member, but the lower heating control member is configured to be shifted with respect to the upper heating control member. Good. Further, the upper heating control member and the lower heating control member may be simultaneously shifted from each other.

Further, as another embodiment, the actuating rod 72 can be driven by using a motor. That is, instead of the operation knob 7 on the front surface of the case, an electric switch (for example,
A push button) is installed, a gear or pulley is installed in the rotation center hole of the operating rod 72, and a power transmission member (gear or belt) that changes the rotation speed by being coupled with the gear or pulley is provided. It is also possible to connect the motor shaft to a motor shaft and drive the motor by an electric switch to reciprocate the heating control member left and right. At this time, the left and right reciprocating motion can be selected by changing the polarity of the electrode of the motor to change the power transmission member.

Further, a solenoid may be used in addition to the motor. In this case, since the attractive force and the repulsive force of the magnet are used instead of the rotating force of the operating rod 72, the rotating shaft and the shaft supporting member are not necessary. That is, a solenoid is installed in the cavity 18 of the right side wall, a permanent magnet is attached to one end of the frame 61a, the polarity is changed by an electric switch, and the upper heating control member 6a is reciprocated left and right. At this time, in order to reduce the impact caused by the collision between the frame 61a of the upper heating control member 6a and the grooves 90, 90 'of the side wall,
A cushioning member (for example, a spring) may be installed at both ends of the frame 61a.

[0032]

Since the present invention is constructed as described above, it has the following effects. That is, it is possible to switch between the oven function and the grill function with a simple configuration of one burner, at least two heating control members, operating means, and operating rods. The present invention can be applied without modification, and the manufacturing cost can be reduced. Further, since the two heating control members are arranged horizontally side by side in the cooking chamber, the space occupied by the heating control means in the cooking chamber can be small, and therefore,
It is possible to sufficiently secure the available space volume in the cooking chamber.
